PK-232 MBX – OPERATING MANUAL MORSE OPERATION
8/91 8-1 100
CHAPTER 8 – MORSE OPERATION
8.1 Overview
The PK-232 will both send and receive International Morse Code. The computer based
Morse operator can use the PK-232 to send "perfect" code at much higher speeds than are
typical of hand sent code. When a computer is used to send and receive Morse Code, you
can also maintain record of your contacts.
As a rule, no computer can receive morse as well as the FSK modes. Your PK-232 is no ex-
ception. A strong signal and a "good" fist are both required for the PK-232 to do a reason-
able job of copying code. Don't expect your PK-232 to do miracles and produce good copy
from bad fists!
8.2 Where to Operate Morse
Before you can operate Morse, you must first know where the activity is. Morse operation is
permitted on any amateur frequency, but most often occurs in the lower 100 to 250 kHz of
a band.
8.2.1 PK-232 Morse Parameter Settings
If you are using an AEA PAKRATT program, follow the instructions in the program manual
to enter the Morse mode.
If you are using a terminal, simply type MORSE or MO from the Command Mode followed
by the <Enter> key to enter the Morse mode. The PK-232 responds by displaying the pre-
vious mode:
Opmode was PAcket
Opmode now MOrse
8.2.2 HF Receiver Settings
Set your HF receiver (or transceiver) to the CW mode. Adjust the volume to a comfortable
listening level. Be certain that any IF-Shift and Passband Tuning controls are centered or
set to the OFF position.
8.2.3 Tuning in Morse Stations
Tuning in Morse stations properly is critical to successful operation.
Follow the procedure below for the best results in tuning in Morse stations.
o Make certain your HF receiver is in the CW mode.
o Turn any IF-Shift and Passband-Tuning controls to the Center or OFF position.
o Tune your receiver carefully in the lower portion of your favorite amateur band and
look for Morse signals.
o When you find a station, slowly vary VFO on your receiver and look for a display on
the PK-232 tuning indicator as shown below when the station is "keyed down".
